Surah Al-Kahf Verse 56 - English Translation by Ahmed Ali
Surah Al-Kahfوَمَا نُرۡسِلُ ٱلۡمُرۡسَلِينَ إِلَّا مُبَشِّرِينَ وَمُنذِرِينَۚ وَيُجَٰدِلُ ٱلَّذِينَ كَفَرُواْ بِٱلۡبَٰطِلِ لِيُدۡحِضُواْ بِهِ ٱلۡحَقَّۖ وَٱتَّخَذُوٓاْ ءَايَٰتِي وَمَآ أُنذِرُواْ هُزُوٗا
We never send apostles but to convey happy tidings, and to warn. But those who disbelieve contend with false arguments to nullify the truth. They make a mockery of My revelations and of what they had been warned
